IMPROVE!) BRICK-PRESS.

The Schedule referred to in these Letters Patent and making part of thelame To all whom 'it 'may concern:

Be it known that I, T. J. BURKE, of Sandwich, in the county of De Kalb,and State of Illinois, have invented certain new and useful Improvementsin Hand Brick-Machines; and I do hereby declare that the fol lowing is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification, and in which- Figure 1represents a perspectiveview,

Figure 2, a side View of the plunger, and

Figure 3, a top view of the plunger.

Similar letters indicate like parts in all the figures.

My invention relates to improvements in brick presses; and to this endconsists in the employment of a plunger, operated by means of a pivotedlever, in combination with such other devices as will be hereinafterfully set forth. v l

To enable others skilled in the art to which my invention appertains, tomake and use the same, I will now describe its construction andoperation'.

In the accompanying drawings A represents a frame, consisting of theside-pieces a a, which may be secured together by means of iron rods,and are provided, between their` upper ends, with a mould or receptacle,b, -for the brick.

bf b are slots made in the side-pieces, the object of which will behereinafter described. Y

a a are plates attached to the sides of the mould, for the purpose ofattaching'the press to the table or bench.

c is a wire frame, secured to the front side of the mould, as seen in g.l.

B represents the plunger, provided at its upper end with theplunging-plate c.

The sidesof the plunger are secured together by the roller d, the endsof which pass through the slots b b in the side-pieces a a, and which isattached at each end, outside the side-pieces, to the lower end of thepivoted frame c e.

D is a roller, pivotedbetween the upper ends of the pivoted frame c e.

This roller is provided with projections e' e'into which is pivoted thecap E by means of the projections f f on the cap and the rod f. u

F is a lever, attached to the roller D.

The operation of my machine is as follows:

The press is first secured in a vertical position to any suitable tableor bench by the plates a a', andthe brick, after being dried, are placedin the mould b; then, by operating the lever F, the pitmen e e force theplate onthe plunger B against the brick in the mould b, and the cap E,covering the upper part of the mould, forms a complete press for thebrick.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is l 1. Thecombination, substantially as set forth, of the pivoted frame e e andplunger B, connected together and retained in their respective places bymeans of the slots b b in the side-pieces a a, as described.

2. The press, consisting of the frame A, provided with side-pieces a aand slots'b' b', pivoted frame e e, mould b, roller D, cap E, lever F,and plungerv B, all combined, arranged, and operating substantially inthe manner and for the purpose described.

In testimony that I claim the foregoing as my own, I ax my signature, inpresence of two witnesses.
